How is Bone Mineral Density Tested?
One of the best ways for a physician to know whether a patient has osteoporosis is through a bone mineral density (BMD) exam. The most popular way to measure BMD is through a quick, easy procedure known as a DXA (Dual-energy X-ray Absorptiometry) evaluation. The DXA evaluation is one of the most recommended ways for a physician to measure bone density. Since early treatment of low bone density helps to prevent future bone fractures, DXA evaluations are recommended for anyone at risk of developing osteoporosis. A DXA evaluation may also be recommended for people with new fractures and are considered at risk for osteoporosis. The exam is easy, painless, and only takes about 20 minutes.
